Dungeon Master: Many Enemies

A Dungeon Master has many
options and many decisions to make when designing combat encounters.
One such decision is about how many enemies to include in an
encounter. Large groups of enemies can give a feeling of tension
while also making the players feel powerful. However, there are some
possible issues with the approach. Rolling can take a while, and it's
possible to end up with a combat encounter that isn't all that
different than fighting one enemy with many attacks, among other
things. Having seen many such situations, I hope to get my thoughts
on the manner recorded. It helps me think through the topic for my own benefit and
hopefully someone, somewhere, finds it useful.

One Enemy

We
could approximate some large groups of enemies by using one that has
multiple attacks. As it takes damage, it gets fewer and fewer attacks
until it finally dies. Now, that can make for an interesting single
creature encounter. The issue I see, however, is that in these cases
there often isn't much of a difference. It would be best if when we
use one or the other, there is a marked difference. The one
difference that does exist is mobility. Many enemies allow you to
restrict movement and also to position them in ways that threaten
multiple people. One enemy fighting a party is the opposite
situation. It is your single enemy that is or can be restricted.

Movement

There
is a lot of potential for enemy movement and clever use of positions
when many enemies are encountered. Some could try to go into tactical
positions, block access to certain routes and force players to hack
their way through, or go around and flank. They don't all need to
move in the same way either. Some can attack at range, some close up,
some could be flying, as well as many other options. This is one of
the major differences from using one enemy. It also means that
multiple people can be engaged while also avoiding opportunity
attacks. If it was one creature attacking everyone in the party, it
would need to move between them and possibly trigger an attack from
every one of them if using melee. It's a bit different with ranged
attacks but we could still get into such a situation when cover is
used. It would also tend to go after one goal, where a large group
lets you go after 2, 3 or even more. I find that a static encounter
is what we want to avoid here. For more on that topic, you can check
my other post here. That one was about confined spaces but the central issue is being locked down in an encounter in both cases.

Carving a Path

When
surrounded and forced to move, not every creature necessarily needs
to be killed. Also, not every goal needs to be chased. The players
could pick one and pursue it fully. They could also choose to escape.
In this kind of case, hacking their way through to escape is a valid
option that isn't otherwise available. A crowd of weaker enemies,
however, makes this a tactical option. Where this can get a bit
tricky is when movement is included. How does it interact with their
attempt to hack through? It's also worth noting that moving through
like this triggers opportunity attacks as well. And with a large
crowd, it would be quite a lot of them. This makes it a rather risky
tactic, though in such a situation risky may be better than certain
death. It's part of the reason why them being weaker is necessary. It
tends to work best with creatures that fall from a single attack or
at least have a good chance to. Player multi-attack, area of effect
spells, or other means to attack more than one creature allow the
players to go through more than one square at a time this way.

There
is another issue when trying to do this. When they break an opening,
initiative order and movement rules can result in a case where the
crowd just catches up to them and tries to swallow them again. There
isn't much of an easy solution in these cases beyond moving away from
combat at that point and handling it as a chase. However, it can
sometimes work out anyway. It partially depends on initiative order.
If it happened just right, the enemies could end up blocking their
own from moving and allow the party to get a good lead on most of
their pursuers. This was a rather cool situation in a game I was a
player in. However, it was probably largely due to luck on our part
and also because zombies don't get as much movement. In our case the
party outpaced the entire group of zombies except one or two. The
other thing to keep in mind is that it would take the enemies more
movement to move around the front of your players. Of course, it also
takes the players some of their movement to escape too. The deciding
factor then comes down to terrain features. A choke point after they
break out can ensure they no longer get surrounded.

Too Many Layers

If we
have too many layers of enemies, it's theoretically possible to
create an encounter where everyone is stuck. It is sort of like the
stalemate situation in the Carving a Path section above. The
difference, however, is that in this case escaping may not be the
goal of the players. However, this can still be a problem because it
restricts movement and therefore tactical choices. You probably don't
want to lock down all your players in a large crowd of enemies that
they can't ever break out of. For this reason just keep in mind how
many layers of enemies you'll be throwing at your players. There is such a thing as too many at once and I believe this is when it happens. To avoid this but still throw large groups at your players, you'll probably need to break them up somehow.

Break Em Up

Having
many enemies allows you incredible freedom in deciding how many will
arrive and when. They all don't have to arrive in a massive crowd.
The encounter can be in multiple waves, or at least what seems like
multiple waves due to initiative order. This allows a turn or two for
players to strategize, get better positions, pick off a few at range,
maybe have a couple rounds of skirmishing, and do whatever else they
need to do.They might still be able to see all the enemies at once. It just might take some of them 3 turns to arrive as opposed to 1.

Identity

Of
course, having more enemies means you have a chance to give each one
their own identity and character. This may make some of them more
obvious targets. It also gives things more personality and allows
some of them to get killed in combat while others retreat. The impact
of this won't be combat related or tactical but it's important all
the same. Some could even turn on each other mid-combat if things
aren't going well.

Rolling A Lot

Many enemies tend to mean a lot of rolling on the Dungeon Master side. It also isn't as easy to handle as other situations. Rolling many dice at once is a common way to speed things up but we'd need to think of ways of assigning the dice to players. If you have 4 or less, having different colour dice ready to go works well. Each colour corresponds to a player so after you roll, you don't need to decide which dice corresponds to who. This way you aren't playing favourites. Of course, you'd need to plan and prepare the dice ahead of time to make sure you have enough. Otherwise, you'll be taking quite a bit of time rolling. Rolling a lot of dice in these cases is unavoidable, just like with enemies that have many attacks. However, how we actually roll them can help save time.
